Find what percent of $39.00 the sale price was. => 15/39*100=38.4% now subtract from 100% to get the mark down percentage. 100-38.4=61.6 Final answer: Marked down 61.6% Hope I helped :)
I believe that she had $852.50. When you multiply 550 by .55(55%) you get 302.50. This is how much she has left. Now you add that to the 550 to get $852.50
